Fluorescent light bulb wattage vs incandescent.
A 9 watt fluorescent bulb in this case is equal to a 40 watt incandescent bulb.
When cfl bulbs were first introduced in the 1970s they were expected to spel.
Watts of electricity used equivalent to 60 watt bulb.
Leds help reduce greenhouse gas emissions from power plants and lower electric bills.
6 8 watts.
A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours.
Fluorescent bulbs vs incandescent bulbs comparison.
Led bulbs require much less wattage than cfl or incandescent light bulbs which is why leds are more energy efficient and longer lasting than their competitors.
How to understand this table look at the lumens brightness in the far left column then compare how many watts of power each light bulb type requires to produce that level of brightness.
When it comes to choosing the right light bulb knowing the differences between them can be helpful in guiding your buying decision now that you know what an led is i bet you re wondering how they compare to traditional light bulbs like fluorescent cfl s halogen and incandescent.
Bulbs only come in certain wattages which make equivalent versions slight different.

Leds require less wattage than cfl for the same amount of light.
The fluorescent lamp and cfl are more efficient in converting electrical energy to light than the incandescent bulb.
An incandescent light bulb s longevity is 2 000 hours on average.
Incandescent bulbs produce a direct light from the heating of the filament whereas the fluorescent bulb produces a secondary light through fluorescent material.
While fluorescent cfl bulbs generate light by sending an electrical discharge through an ionized gas incandescent bulbs emit light by heating the filament present in the bulb.
Designed for bathroom vanities or anywhere a globe bulb is required these bulbs produce light equivalent to a 40 watt incandescent bulb yet only consume 10 watts of power.
To achieve the same brightness as a 60 watt bulb you would only need a 13 15 watt fluorescent bulb or a 6 8 watt led bulb.
Differences will also occur between types and sizes of light bulbs.
Due to a physical process that is utilized in incandescent bulbs they are sensitive to voltage changes.
